How canal works to allow a boat to travel uphillCanal LocksWhat is isometric projection drawing technique explained with an example of the Bauhaus Dessau buildingIsometric projectionOrbit illustration: how a satellite stays in orbit - the balance between its velocity and gravity pulling it towards EarthOrbitThe Swiss Cheese Model illustration: A stack of 4 vertical Swiss cheese slices act as safeguarding protective layers, keeping a young family on the right of the stack safe from the harmful elements approaching from the left. Although the holes in the cheese slices allow penetration through some of the barrier, the multiple layers, with unevenly distributed holes, prevent harmful elements breaking all the way through. The Swiss Cheese ModelWhat is Jevon's paradox: fuel use tends to increase, not decrease, despite efficiency gains. Observation from William Stanley JevonsJevon’s ParadoxAccuracy and Precision illustration: 4 circular targets with red dots marking a series of strikes show the difference between accuracy and precision. Accuracy and precisionWhat is Rubberducking? Example explanation: a developer talks through their problem with the “therapist” rubber duck on their desk, only to discover the insight they need.
